The phenomenon of Mo undercut and Cu loss is generally discovered during the manufacturing process of LCD display, which could be explained by galvanic corrosion of Mo followed by crevice corrosion of Cu. If Mo is replaced with more antioxided and anticorrosive ones, the above problems can be fundamentally solved.
